The city of Urânia has been experiencing contamination problems in the Adamantina Aquifer since the 1970s, like many urban areas in São Paulo. It is extremely important to detect and monitor contaminated environments for prevention and repair, but one of the limitations is the limited access to the aquifer, especially establishing aquifer levels and the lithological characteristics of the unsaturated zone. This work identifies the aquifer recharge areas in Urânia most susceptible to anthropic degradation, by electroresistance contrasts. Vertical Electrical Surveys (VES) and Electrical Profiling provided a representative electrical dataset of the municipality. VESs and monitoring wells supported calculating the Dar Zarrouk Longitudinal Conductance Parameter and, further, the vulnerability index. The investigation also counted with other aquifer characteristics, such as its type, water level and lithology of the unsaturated zone. The resistivity profiles obtained by the Electric Walks showed values below 0.5 Ohm.m in the northeastern part of the city, close to the aquifer discharge region, where there is a concentration of organic contaminants. The vulnerability map indicated the southeast area as the most prone to contamination due to its permeable geological material and low thickness of its unsaturated zone. Low resistivity anomalies (<0.5 Ohm.m) were compared to previously published chemical analyzes, corroborating with their assessments, and showing the aquifer contaminated areas in and around the urban area of Urânia.
